Synthetic grain-leather with woven layer

ABSTRACT

A synthetic grain-leather with woven layer has a split layer, a bonding layer, a woven layer and a surface layer. The split layer has a coating surface. The bonding layer is coated on the coating surface. The woven layer has multiple interwoven fiber structure and is bonded on the bonding layer. The surface layer is attached to the woven layer. Therefore, the woven layer increases a structural strength of the surface layer and prevents wrinkling to maintain a smooth appearance of the synthetic grain-leather with woven layer.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a synthetic grain-leather, and moreparticularly to a synthetic grain-leather with woven layer.

2. Description of Related Art

An animal pelt comprises a grain side leather and split layer. Due tothe thickness problem it is leather always need to be split two parts,one is the grain side leather and the other is the split layer. Thegrain side leather can be processed into higher quality product ofleather, but the split layer can not be processed same quality product.Because the drop split don't have the fine and smooth grain surface, itjust has coarse and multiple holes surface, so is normally use the dropsplit to make suede. Alternatively, to raise a value of each split, thesplit synthetically processed to achieve a similar appearance tograin-leather. With reference to FIG. 5, a synthesized grain-leather(90) comprises a split layer (60), a bonding layer (70) and a surfacelayer (80). The bonding layer (70) is coated on the split layer (60) tofill up depressions or holes of the split layer (60).The surface layer(80) is resin, is coated on the bonding layer (70) and has been made toform grains similar to grain-leather.

However, because the structural strength of the split layer (60) and thesurface layer (80) are weak, the synthesized grain-leather (90) may showan orange peel surface when the synthesized grain-leather get a strongtensile force.

To overcome the shortcomings, the present invention tends to provide asynthesized grain-leather with woven layer to mitigate or obviate theaforementioned problems.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a syntheticgrain-leather with woven layer to increase a structural strength and tokeep from an orange peel appearance of a surface layer.

A synthetic grain-leather with woven layer has a split layer, a bondinglayer, a woven layer and a surface layer. The split layer has a coatingsurface. The bonding layer is coated on the coating surface. The wovenlayer has multiple interwoven fiber structure and is bonded to thebonding layer. The surface layer is attached to the woven layer.Therefore, the woven layer increases a structural strength of thesurface layer to prevent wrinkling and maintain a smooth appearance ofthe synthetic grain-leather with woven layer.

Other objects, advantages and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

With reference to FIG. 1, a synthetic grain-leather with woven layer inaccordance with the present invention is between 1.0-1.2 mm thick andcomprises a split layer (10), a bonding layer (20), a woven layer (30),a surface layer (50) and an adhesive layer (40).

The split layer (10) comprises a coating surface (11). The coatingsurface is coarse and has multiple holes.

The bonding layer (20) may be polyurethane and is coated on the coatingsurface (11) to fill the holes of the split layer (10).

The woven layer (30) may be polyester or other similar materials, hasmultiple interwoven fiber structure and is bonded on the bonding layer(20).

The surface layer (50) may be varnish or polyurethane , is attached tothe woven layer (30) and comprises an inner surface (51) and an outerlayer (52). The inner surface (51) is attached to the woven layer (30).The outer layer (52) has multiple grains formed in the outer layer (52).

With reference to FIGS. 2 and 3, the adhesive layer (40) is coatedbetween the woven layer (30) and the surface layer (50) and may be acomposite resin synthesized from a polyurethane resin, an acrylic resinand a paint. With reference to FIGS. 4A to 4E, a manufacturing method ofsynthetic grain-leather with woven layer in accordance with the presentinvention comprises a pre-treatment of softening the split layer (10),and coating the bonding layer (20) on the split layer (10); drying thenbonding the woven layer (30) to the bonding layer (20) by hot pressingbefore optionally coating the adhesive layer (40) on the woven layer(30); drying then attaching the surface layer (50) to the woven layer(30), maybe using the adhesive layer (40); and softening process to formthe synthetic grain-leather with woven layer.

Therefore, a structural strength of the synthetic grain-leather isincreased by. the woven layer, which also prevents wrinkling to maintaina smooth appearance of the surface layer (50).

Even though numerous characteristics and advantages of the presentinvention have been set forth in the foregoing description, togetherwith details of the structure and function of the invention, thedisclosure is illustrative only, and changes may be made in detail,especially in matters of shape, size, and arrangement of parts withinthe principles of the invention to the full extent indicated by thebroad general meaning of the terms in which the appended claims areexpressed.
